What does encrusted mean?
Encrusted describes something covered with a hard, adhering outer layer — a surface that has become coated over time or by design. A diver might find a shipwreck encrusted with barnacles and coral; a hiker's boots may return home encrusted with dried mud; a cathedral reliquary may gleam, jewel-encrusted, behind glass. The word is neutral about what forms the crust: it can suggest neglect and accumulation, as with salt-encrusted windshields or grime-encrusted machinery, or it can signal opulence, as in gem-encrusted crowns and ceremonial armor. It typically appears either as an adjective before a noun or after a linking verb, most often followed by 'with' to name the coating material. Derived from the verb encrust, which traces back through French to Latin crusta, meaning a hard outer shell, encrusted shares ancestry with words like crustacean and custard. Its vividness lies in implying a layer that has hardened and become part of the thing itself.
Covered with a hard outer layer or coating of something, such as dirt, salt, ice, or jewels.
"The rocks along the shore were encrusted with white salt deposits."
Almost always takes the preposition 'with' to specify the covering substance.
Past tense and past participle of encrust: to cover with a hard outer layer.
"Years of mineral deposits encrusted the inside of the old pipes."
A jewel-encrusted crown and a rust-encrusted pipe share the same verb — English doesn't care whether the crust is treasure or grime.

Etymology of encrusted
Encrusted is the past participle of the verb encrust, which entered English in the early 17th century from French encroûter, ultimately deriving from Latin crusta, meaning a hard outer shell or rind. The same Latin root gave English the noun crust, as well as crustacean (animals with hard shells) and, via Old French crouste, custard and crouton. The variant spelling incrusted, formed directly from the Latin prefix in-, persists especially in British usage but is less common today.
